…and I’m not really trying to tell you you’re wrong either.
however, my faulting wiring requires I point out that 1ml of distillate is only approximately 1g
if we were talking water, then at one point 1gram == 1ml (1 cubic cm!) was the definition.
Originally defined as “the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm3], and at the temperature of melting ice”[2] (later at 4 °C, the temperature of maximum density of water). However, in a reversal of reference and defined units, a gram is now defined as one thousandth of the SIbase unit, the kilogram, or 1×10−3 kg, which itself is now defined by the International Bureau of Weights and Measures, not in terms of grams, but by “the amount of electricity needed to counteract its force”.[3]
for crude or distillate its a handy estimate, but you should always remember it’s an approximation
